Two University of Washington students have come up with an app called Canary that allows medical marijuana patients to order pot and have it delivered to their door.

"The easiest way we say it is that it's Uber for marijuana," co-founder Josiah Tullis said in an interview with KIRO-TV in Seattle.

Canary will be offered to medical marijuana patients in Seattle next month, with plans to expand to Denver and California, KIRO reports.

Patients will have to send in a picture of their medical marijuana card when they sign up, and they will have to show their card again at the time of delivery, according to KIRO.

Currently, Washington and Colorado are the only two states with legal recreational marijuana. Tullis and his partner, Megh Vakharia, told KIRO they want to expand the app to recreational marijuana in Washington, but state law prohibits it.

Canary will partner with local dispensaries and hire the drivers. It's likely that five to 10 dispensaries will be signed on by the Seattle launch, with the goal of expanding to 20-30 dispensaries, Vakharia said in an e-mail to USA TODAY Network.

The service is 24/7, as long as a dispensary is open, and delivery is usually within an hour, according to the app's website. Initially, there will be a 10%-25% surcharge for patients per delivery, but Canary's founders are exploring other payments, including a flat fee or charging the dispensaries a fee after they have gained a sufficient number of customers through the app, according to Vakharia's e-mail.
